PGA309 EVM Configuration
* When we want to use current output mode of
XTR117:
* we should make sure the configuration of
PGA309 is in 4-wire voltage output mode;
* Because in 3-wire voltage output mode of PGA309, we should turn on/off the Vs of PGA309. But in 3-wire mode, the one-wire and
Vout is connect in one junction, so we cannot
use one-wire to control the Vs (turn on/off).
* conclusion:
is we should use 4-wire voltage output
for current output.
